Add the projects from the website (htdocs/contrib/projects.xml).
At this point, all this is is a "blind conversion" from the xml file to
individual mdwn files. I did this by using a custom xslt file and some
manual cleanups on the files.
Most of these projects are still misclassified as they do not list the
correct difficulty or the category they list is not yet defined in the
wiki. Some other projects need to be pruned out due to the lack of
details (or moved to the ideas page). But this is a "good enough" start
that should allow me to nuke these same projects from htdocs.
